SEPARATING-TRAI.

To @ZZ fte/om t may concern.'

e it known that I, lViLLrair A. SHORB, a citizen of the United States, resident of ecatur, in the county of Macon and .State of Illinois/.have invented new and useful Improvements in Separating-Traps, of which the following is a specilication.

in a separating trap, and the ebgect is to provide a simple and eiective construction of this type for separating the oils from water, and also for separating any solids which may be present in the mixture.

ln numerous communities and municipalities, ordinances and regulations are in eilect, requiring the installation in buildings, such as garages and the like, of traps for separating the oils, gasolene or other hydro-carbone from the drainage water so as to prevent the passage of hydro-carbon into the sewerage system and prevent possible explosions and damage from other causes.

Another object of this invention is the provision of such a device which includes means for collecting and removing the sediment or solid matter and also a pump for removing the oil, gasolene or other hydrocarbons, and a connection whereby the pump may be used to remove the water from the lower part of the tank for cleaning purposes.

o the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists in the combination. construction and arranfrement of parts hereinafter described and then sought to be delined in the appended claims, reference being had to the accompanying drawings forming a part hereof, and which shows merely for t e purpose of illustrative disclosure, a preferred embodiment of my invention, it being understood that various changes may be made in practice within the Scope of the claims without digressing from my inventive idea.

In the drawings,

Figure l represents a vertical section taken through a separating trap constructed according to my invention;

ig. 2 is another vertical section taken on a plane at right angles to the plane of Fig.

full lines in cone pipe whereby the oil and other hydro-carbons may be removed, and in dotted line position in connection with Specicaton of Letters Patent.

the pipe through which the moved from the tank;

iig. is a horizontal section taken substantially on line 3`3 of F ig. l.

Broadly considered, this prises a tank which is adapted to in a suitable pit connected to the drainage system of a garage or other building which is drained therefrom. Tiis liquid is a combination of water, lene and dirt of various kinds. therefore means ing the sediment or heavier substances, and has a discharge compartment having its opening near tank so that the water forms a seal and will pass through the outlet into sewersystem. i connection is provided within the tank extendingr to a point near the water level and another connection is extended into the tank to a point near the bottoni thereof, and practically in plane with the end of the discharge compartment or passage. A pump is adapted to be attached to either of these connections so as to withdraw the oil or other hydro-carbon water is to be reand also to withdraw the major portion of the water in the bottom of the tank, when desired. At is preferred that this tank be placed in a cement pit, th which is provided with the lar fom to receive a plate same form.

rlhe tank or trap proper l, is preferably c iflindrical in shape, having the inlet coupling 2 with the downturned elbow 2 side and the outlet coupling 3 at the other side. These couplings are located substan tially on a line with each other so that the water line is the lower edge of the coupling.

Supporting frame 4 is provided on which the removable bucket or other receptacle 5 rests below the coupling 2, so that the fluid in passing into the trap, iirst falls into this removable bucket or receptacle, the dirt and other heavierl substances falling to the bottom thereof by gravity, and the liquid passing ofi" into the other part of the tank. Surrounding the outlet coupling' 3, and extende upper edge of T-iron of annu` or cover of the ing from the top 6 of thetank to near the bot-Y tom 7. is the discharge compartment or passage 8.

The top 6 of the tank is provided with the lOO ` ing through l the insertion of some means this discharge The man-hole 6 to cover the to permit acvented plug 9 opening into compartment or passage plate 10 is bolted to the top opening leading thereinto, cess.

Extending downwardly from one side of the top is the pipe connection 11 which is connected to the double coupling 12 in the top, and has the cup mem er 13 adjustabl y mounted on its lower end, as by means of a set screw or the like. rlhis pipe connection 11 is 'adapted to be normally closed by means of a plug which is readily removable to permit the application of the connection 1d forming a part of the hand pump 15, as shown in full lines in Fig. 2. lt is to be noted that the cup 13 on the lower'end of pipe connection 11, has its inlet opening positioned just above the water line so that when the pump is applied and operated, practically all of the oil and other hydro-carbon which iioats on the water, maybe removed. On vthe other side of the top is provided the pipe or connection 16, connected to the coupling 17, similar to the other coupling 12, and this pipe or connection extends down on a line with the-inlet to the discharge passage or compartment 8, so that when the pump is connected thereto,as indicated in dotted lines in ii`ig.2,the water may be pumped from the tank down to that level. The vent opening 18 is provided in the side of the tank, and adapted to be connected to a pipe which leads through the roof or to the outside of the building, as sometimes required by regulations, ordinances or statutes.

The water seals the inlet to the outlet 'passage or compartment 8, so that the oil, gasolenel or other hydrocarbon is entirely separated therefrom and remains in the upper portion of the tank, the water passthe outlet and leaving the oil, gasolene or other hydrocarbons within the tank until removed by the application and operation of pump 15.

This structure is effectively taken care of with a minimum amount of trouble and conforms to the requirements of standard ordinances, regula* tions and other statutes. Another use for the plug 9 ,is to permit for sampling the water in the discharge compartment or passage 8, so as to be sure that the trap is iroperly performing its function of removing the oils, greases and the like.

Vhat I claim is z- 1. A separating trap,

simple and` may be including in combination a tank having an inlet connection andan outlet connection, a discharge compartment or passage inclosing said outlet connection and extending from the top of.

the tank to a point near the bottom of the tank, .a removable receptacle located beneath the inlet connection adapted to rrceive the solid matter, a pipe connected to the top of the tank and leading to a point just above the water line and adapted to receive a pump so as to remove the oil and other hydro-carbon therefrom, and another pipe leading from the top of the tank to a point in the same plane as the lower end of the discharge compartment or passage and adapted to receive a pump for removing the water from the tank.

2. ,A separating trap, including` in combination a tank having an inlet connection and an outlet connection, a discharge com` partment or passage inclosing said outlet connection and extending from the top of the tank to a point near the Vbottom of the tank, a ren'iovable receptacle located beneath the inlet connection adapted to receive the solid matter a "n e connected to s Al the top of the tank and leading to a point linst above the water line and adapted to receive a pump so as to remove the oil and other hydro-carbon therefrom, and another pipe leading from the top of the tank to a point in the same plane as the lower end of the discharge compartment or passage and adapted to receive a pump for removing the water from the tank, said discharge compartment or passage being provided with a vent and said tank also beingprovided with a vent, both vents being located near the top of the tank.

3. A separating trap of the character described, including in combination a tank, having an inlet connection and an outlet connection located in substantially the same plane, a removable receptacle positioned'beneath said inlet connection and adapted to receive the solid matter, a discharge pas sage or compartment embracing said outlet connection and extending Afrom the top oi' the tank to a point near the bottom there of, said discharge compartment or passage having a vent therein, a pipe leading from the top of the tank to a point just above the water line therein and having an inlet member adjustably mounted on its' lower end, with its inlet opening above the water line, and another pipe leading from the top of the tank to a point near the bottom thereof in substantially the same plane as the opening into the discharge passage or compartment, said pipes being adapted to receive a pump for the removal of liquids in the tank down to the level of the lower end of the pipes.
